FIELD: construction.SUBSTANCE: device comprises guides, in which a mechanism moves, generating mechanical vibrations transferred to cover elements, in the form of strips of meshy material, for example, connected with elastic plates. Vibrations sent to strips and plates result in snow dropping from them and damage of icicles formed on the edge of elastic plates. The mechanism - generator of vibrations - is controlled remotely and obtains power supply via contacts in guides. Guides with a pulse mechanism are placed at the upper levels of the roof.EFFECT: improved people safety on a roof in process of its cleaning in winter time.3 cl, 1 dwg |
